什么是惯用的方式做在Delphi异步套接字编程？ [英] What's the idiomatic way to do async socket programming in Delphi?

问题描述

什么是正常的方式人民德尔福使用Windows风格的重叠的异步套接字编写网络code I / O？

What is the normal way people writing network code in Delphi use Windows-style overlapped asynchronous socket I/O?

下面是我之前研究这个问题：

Here's my prior research into this question:

href=\"http://indyproject.org/\">印成分似乎完全同步的

The Indy components seem entirely synchronous. On the other hand, while ScktComp unit does use WSAAsyncSelect, it basically only asynchronizes a BSD-style multiplexed socket app. You get dumped in a single event callback, as if you had just returned from select() in a loop, and have to do all the state machine navigation yourself.

在.NET形势相当更好，与Socket.BeginRead / Socket.EndRead，那里的延续，是直接传递给Socket.BeginRead，而这也正是你再爬起来。的延续codeD作为一个封闭显然有需要，而所有上下文等等。

The .NET situation is considerably nicer, with Socket.BeginRead / Socket.EndRead, where the continuation is passed directly to Socket.BeginRead, and that's where you pick back up. A continuation coded as a closure obviously has all the context you need, and more.

推荐答案

有关异步的东西尝试ICS

For async stuff try ICS
